It's not a buzzword, it's a very salient point. Code reuse, a consistent UI and a much greater development velocity across a much greater number of platforms (web, desktop, mobile). It can be done poorly, and there are plenty of examples of that, but it's not a universal rule and the trade-off gives real benefits. At the end of the day you do need to ship and maintain _something_, and maintaining one thing is better than maintaining Web, MacOS Desktop, Windows Desktop, Linux Desktop, iPhone and Android.
